Methodologies and Tools for Virtual Knowledge Graph Design
This tutorial addresses a significant challenge in complex data-intensive tasks: the coherent integration and access to heterogeneous legacy data sources through Virtual Knowledge Graphs (VKGs). FOIS participants will find the topic particularly attractive as VKGs provide, via declarative mappings and an ontology, a bridge between legacy data sources and real-world data analytics and machine learning applications. As such, they emphasize practical ontology usage beyond traditional semantic tasks. The tutorial is novel because it specifically targets the critical yet under-explored aspect of VKG mapping layer design, a bottleneck currently lacking established methodologies and tooling support.
Participants will explore a structured approach to VKG mapping design through a comprehensive catalog of mapping patterns reflecting best practices. Attendees will also gain hands-on experience with innovative tools, both open-source ones and developed by Ontopic, designed to automate and simplify the creation and refinement of VKG solutions. Key learning outcomes include an in-depth understanding of VKG fundamentals, practical skills in mapping pattern application, experience with state-of-the-art VKG tooling, and enhanced capabilities in addressing real-world data access challenges. This tutorial promises to equip participants with both theoretical insights and practical methodologies essential for advancing their
data-intensive ontology-driven projects.
